Structure of the laser tube
：
it is the most important part of the laser equipment. Usually adopt hard glass and with
layer structure. The most inside part is power pipe, the second layer is water cooling pipe, the most outside layer for
gas. The thickness of power pipe has non business with the our put laser power, mainly considering for the diffraction
effects caused by laser light spot, should be determined according to length of tube.
Longer tube will be a little thicker, shorter tube will be a little thinner. length and output power is proportional. Within
a certain length scope, every meter power pipe increases the power as the length increasing. The two sides of power
pipe connect with gas pipe, that mean there is one hole at one side for them to connect, at the other side connect via
Tracheal spiral. Then it could make the gas Cycle between power pipe and gas pipe, and change the gas at any time.
The function of water-cooled jacket is to cool the gas and make the output power stable.
z
The model of laser tube is usually decided by laser power, the normal model is: 15W
、
25W
、
40W
、
60W
、
80W
、
100W
、
120W
、
130W
、
150W
。
z
Laser tube with different laser power with different length, such as 60w laser tube is 1200mm or 1.25mm, 80w is
1600mm.

Installation of the laser tube
：
1). The laser tube is glass material and fragile. Remove the screws with the allen wrench (in the toolbox), put the
laser tube onto the two bases. The side of the laser tube which sending out laser should face the first reflecting
mirror. The distance between the side of the laser tube and the first reflecting mirror is 2-5cm. Fix the tube with the
clips.
1 Clip ring of laser tube
2 is full reflected mirror

Installation of the pipes of the water chiller
a) The inlet water pipe is towards the earth while outlet pipe towards the sky. Turn on the water chiller, check if
there are bubbles in the tube after one minute cycling of the water. If bubbles coming out, please loose the clips of the
tube and rotate the laser tube to extrusion the bubbles.
b) The laser tube should avoid generating incrustation which would cause water stemming. If there is incrustation,
please clean it with 20% diluted hydrochloric acid.
